Unused. If specified, will default to BEST_GUESS. |
BEST_GUESS |
Indicates that the returned duration should be the best estimate of travel time given what is known about both historical traffic conditions and live traffic. Live traffic becomes more important the closer the departureTime is to now. |
PESSIMISTIC |
Indicates that the returned duration should be longer than the actual travel time on most days, though occasional days with particularly bad traffic conditions may exceed this value. |
OPTIMISTIC |
Indicates that the returned duration should be shorter than the actual travel time on most days, though occasional days with particularly good traffic conditions may be faster than this value. |
